Abstract
The invention relates to a cyhalofop-butyl and sulfonylurea herbicide-containing herbicide composition. The composition is mainly characterized by comprising 1 to 60 percent of cyhalofop-butyl, 1 to 60 percent of sulfonylurea herbicide, an auxiliary agent and other excipients, wherein the herbicide composition is prepared into wettable powder, water dispersible granules, a suspension agent, suspending emulsion, microemulsion and water emulsion. The herbicide composition is used for preventing and treating annual gramineous weeds of paddy fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to the Herbicidal combinations of a kind of cyhalofop-butyl and sulfonylurea herbicide, be used to prevent and treat paddy field barnyard grass grass, moleplant seed, grassy weed.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", promptly (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active height; (3) selectivity height.Therefore continue to improve the performance of present Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of valid approach, be that the agricultural chemicals of performance complement obtains best synergistic effect by the proportioning of adjusting different agricultural chemicals.
Cyhalofop-butyl (cyhalofop-butyl), molecular formula: C

7S, relative molecular mass 434.8 is sulfonylurea herbicides of Monsanto Company's exploitation.Absorb by weeds root and leaf, conduct in the plant body, weeds promptly stop growing, and are then withered.Halosulfuronmethyl in making object in rapidly metabolism be harmless object, so to crop safety.
The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.Therefore, they kill careless ability and scope is also different.It is narrower that some weed killer herbicide kills the grass spectrum, but have one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
Nineteen fifty-five has the people to report that Amrol can increase the prevent and kill off effect beginning of dalapon to the stone thatch, after, along with further developing of weed killer herbicide production and application, using with gradually between the weed killer herbicide grows up.China also comparatively payes attention to using with aspect the research of weed killer herbicide, is recognized extensively that to do be one of important measures of rationally using of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained bigger progress.
My company also is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers with the relevant composite product of azimsulfuron, cinosulfuron, AC322140 or halosulfuronmethyl about cyhalofop-butyl.
